While a pair of teams have dominated the MAC over the past decade (Northern Illinois and Central Michigan have combined for six MAC titles and nine MAC Championship Game appearances), fortunes for other teams in the conference seem to change on a regular basis. For example, in Frank Solich’s second season, Ohio improved from 3-5 in conference play to 7-1 and won the division. They dropped to 4-4 and 3-5 over the next two seasons before rebounding once again to 7-1. Miami of Ohio has enjoyed several zeniths and nadirs, finishing 2-6 in 2006, 5-2 (and division champ) in 2007, and back to 1-7 in 2008. They were 1-7 again in 2009 before jumping to 7-1 (and conference champion) in 2010. Buffalo jumped from 1-7 to 5-3 in a single season and Bowling Green fell from 6-2 to 1-7 before rebounding to 6-2 just two years later. Even entrenched powers like Northern Illinois and Central Michigan have seen losing seasons begat bowl trips and conference titles begat losing campaigns. I could go on, but you get the idea. In the MAC, very little is permanent. Why? Could it be because MAC school are fighting for the scraps of (mostly) Big 10 schools that their talent levels are very close together thereby making randomness a much bigger determinant of success in the MAC than other conferences? That is certainly a possibility. One idea I had was to look at the average point differential in conference games for each of the ten conferences playing in the FBS last season. The results are summarized below with commentary to follow.
